are hard to get. Mostly small Orthoceras.
Then 13 1/2 feet of chalky limestone that
weather into a nodular limestone. There are
many fossils that show no weathering but few
can be had that have any value. Syngonina
Kentuckensis is common and there are Trivalves
and gastropods. Saw no coral other than a
single Strophomena adustum.
Then came regular bedded li with shale
faster down to base line, 28 1/2 feet. These beds
became more and more prolificous. Those collected
at the bottom
are marked zone (3), and those near the top are
zone (2). In zone (2) I also a single R. capay
and Str. morona filitexta. In zone (3) Orthus
insculpta, Strophomena nusta and Fairstella
stellata are the most common fossils. Bygnea
are also common but all are in slabs.
The Richmond seen this morning measures
83 feet and is essentially a limestone - then bedded-
slabs with lots little shale. The shale increases
in amount towards the bottom and here the
fossils are also more common. Orthus insculpta
appears to be restricted to the lower 28 feet.
